merely for lighting or incandescent purposes, or merely for heating purposes, but it may also be used jointly for both purposes.

The heater is of that type known as a Bunsen burner, and, accordingly, is very eflicient and economical in operation. In practice, it is provided with a support whereby various materials may be heated directly by it, or another device may be applied thereto when it is desired to radiate the heat therefrom, such, 0. 9., as is the case when it is desired to heat a room.

The invention is of a simple and compact construction, may be manufactured economically, and, in practical operation, has been demonstrated to possess marked utility.

The device does not require any particular construction of gas fixture, but may be screwed on to any ordinary gas bracket.

A particularly important feature of the invention consists of a gas cook so constructed as to supply gas to one, or more, or all, of the burners or heaters; said construction, in its preferred form, consisting of a cock or valve provided with a plurality of bores, the inlets and outlets to which are enlarged. The enlargements to these inlets and outlets are so constructed that after one lighter or burner is ignited it is impossible for gas to escape from any one of the other lighters or burners without being automatically ignited by the lighter or burner previously lighted. It is impossible, therefore, for gas to escape, unignited, from any of the burners or lighters so long as one of said burners or lighters is ignited.

Various important features of theinvention, not heretofore adverted to, will be apparent from the following detailed description of the invention, and the accompanying claims taken in conjunction with the drawings.

In the accompanying drawings I have illustrated different practical embodiments of the invention, but the constructions shown therein are to be understood as illustrative,

only, and-not as defining the limits of the invention.

Figure 1 shows the device in side elevation. Fi 2 shows the device in front elevation, with a small portion thereof in section. Fig. 3 is a sectional elevation on line 33 of Fig. 2. Fig. 1 is a perspective view of a hood or deflector which may be used on the device. Figs. 5 to 11, both inclusive, show, in section, different positions of the gas cock or valve on line ar-zv, Fig. 3. Figs. 5 to 11, both inclusive, show, in section, different positions of the gas cook or valve on line I/fl/, Fig. 3. Figs. 5 to 11 both inclusive, show, in section, different positions of the gas cook or valve on line 22, Fig. 3. Figs. 12 and 13 show modifications of the device illustrated in Fig. 1, and Fig. 11 is a plan of the device shown in Fig. 12.

Referring particularly to Figs. 1 to 11 both inclusive, of the drawings, B represents a gas burner or heater of the Bunsen type, hereinafter termed a burner, and an illuminating burner or gas jet, hereinafter termed a lighter, both of which are supplied with gas through a valve, designated in its entirety as C, and to which valve is connected a main gas supply tube, D. An

extension nipple, E, is also supplied with gas fromvalve, C, and to such extension any suitable burner or lighter may be connected.

urner, B, is provided near its base with air inlet holes, 0, and near its top with outlets for air and gas, (Z, and carried by or associated with said burner is a suitable supporting device having standards, 6, and a top disk, f, which is adapted to support any article which it is desired to heat.

hen it is desired to deflect the heat from the burner downwardly a hood or deflector, F, see Figs. 2 and 1, may be applied to disk, 7, and supported thereon by means of an inwardly projecting flange, g, on said deflector. j

1 The gas jet or lighter, L, is provided with the customary tip, 71..

The gas valve, C, see Fig. 3, is provided with a valve casing, 2', which is connected with gas pipe or main, 1), by means of an elbow, i and nipple, 2' The casing i, Which forms a seat for the valve proper, G, has a plurality of inlets, here shown as three, Z, Z Z and a plurality of corresponding outlets, a, n m the respective inlets and outlets being adapted to be placed into or out of communication by means of valve, G, which contains three bores or passages, 0, 0 0

Valve, G, is provided with the usual thumb piece or turning member, 22, and the end of the valve casing adjacent thereto may, if desired, contain a scale or indicator, 5;, adapted to cooperate with a pointer, 1 affixed to valve, G, for the purpose to be hereinafter described.

, An important feature of the invention consists in the function performed by valve, G, due, in the present instance, to the novel structure of said valve herein detailed, although it will be understood that this function may be performed in other ways than that specifically described.

Figs. 5 to 11, both inclusive, are taken through valve, G, and centrally of inlet, Z and outlet, 71 leading to lighter, L, and show the several positions of the valve with reference to inlet Z outlet, n and bore, 0 Figs. 5 to 1 1 both inclusive, are taken through valve, G, and centrally of inlet, Z and outlet, of, leading to extension, E, and show the several positions of the valve with reference to inlet, Z outlet, W3, and bore, 0 and Figs. 5 to 11*, both inclusive, are taken through .valve, G, and centrally of inlet, Z, and outlet, at, leading to burner, B, and show theseveral positions of the valve with reference to inlet, Z, outlet, 11/, and bore, 0.

It will be observed that the inlets and outlets to bores, 0, 0 and 0 respectively,

- are enlarged by cutting away or grooving the face of the valve, as indicated by the enlarged bore inlets, s, 8 and s, and enlarged bore outlets, t, and t see Fig.

3 and Figs. 5 to 11 The advantage of enlarging the inlet and outlet to the several bores will be readily apparent from an examination of the drawings, Figs. 5 to 11', from which it appears that in order to get a flow of gas through any particular passageway or bore in the valve it is not necessary that the narrow portion of said bore, 6. 9., bore, 0 see Fig. 6, be in direct alinement or register with gas inlet, Z and gas outlet, a respectively; since if the said gas inlet, Z communicates with any part of the enlarged portion, 8 of bore, 0 and the gas outlet communicates with the enlarged part, 6 of bore, 0 a flow of gas will be established to lighter, L. By similarly positioning the valve, as shown in Fig. 10*, a flow of gas is established to burner, B. V

In connection with Figs. 5 to 11*, I have noted on the left of said figures the letters, C, L, 'B and E, to designate, respectively, that the valve is entirely closed, or is supplying gas only to the lighter, or only to the burner, or only to the extension. Where two or more letters are used, it indicates that the valve is positioned to supply either the lighter and burner together, the extension and burner together, or the lighter, burner and extension simultaneously. Thus beginning at the top of sheet 2 and reading from left to right, we see the position of the valve when closed; on the next line, its position when supplying the lighter, L; on the next line when supplying the lighter, L, burner, B, etc., through the various six other positions indicated.

It will be noted that when valve, G, is rotated from its closed position, Figs. 5, 5 and 5 in the direction of the arrow, the gas is first turned on to the lighter, L, Figs. (5, 6 and 6 then, successively, by a further 1'0- tation of 30 degrees each time, to the lighter, L, burner, B, Figs. 7 7 and 7"; lighter, L, extension, E, and burner, B, Figs. 8, 8 and 8"; extension, E, and burner, B, Figs. 9, 9" and 9; burner, B, Figs. 10, 10 and 10"; ex-

tension, E, Figs. 11, 11 and 11 and finally,

by a further forward rotation, or by a backward rotation, to closed position again. As

long as one lighter or burner remains lighted, any subsequent position of the valve to admit a supply of gas to another burner or lighter, will cause the latter to be automatically ignited by reason of the proximity of the lighters and burners to each other; and while only one burner or lighter remains ignited, or even two or more, there can be no passage of gasto a burner or lighter which it is not intended to ignite.

If desired, the several operative positions of valve, G, as well as its closed position, may be secured by means of the indicator, 9, and pointer, 7 heretofore described, although in practice I have not found it necessary to use them.

It will be understood that the novel type of valve just described, and which might be termed a compound valve, may be used for controlling the flow of water, steam or other fluid from a common source of supply or inlet to a plurality of outlets, or vice versa, and that it may be provided with additional openings or bores to those described, or even restricted to two such openings or bores.

In Figs. 12 and 14 I have illustrated a modification of the invention heretofore described in that I have shown the device as embodying two burners or heaters, B and B with a lighter or gas jet, L, said burners and lighters being triangularly arranged. In this construction, also, a disk, f, is supported on the standards or supports, 6, 6 (corresponding to standards, 0, 0), provided with openings, into which extend the tops of burners, B and B the small diameters of said burners being indicated in Fig. 14 by i Otherwise, said device has a corresponding valve, C, and operates in substantially the same manner as.

the one previously described- The modification shown in Fig. 13' is substantially the same as that illustrated in Figs. 1 to 3 in that it has a burner or heater, B an extension, E, a lighter, L, gas valve C standards, 6 and disk, F. The essential difference of construction in this modification consisting in locating the lighter, within the burner, B and having its tip, extending above disk, Other wise the operation and construction of this type of burner is the same as those heretofore described.

It will be understood, of course, that various modifications of the invention other than those described may be made without departing from the spirit or substance of the same.

Having thus fully described the invention, what I claim as new, and desire to se cure by Letters Patent is:

1. In a device of the class described, a valve-controlled gas inlet, an illuminating burner connected therewith, and a Bunsen burner, provided with an attachment for supporting an article to be heated, also connected therewith and in such close proximity to the illuminating burner that when gas is ignited in the illuminating burner, and gas turned on to the Bunsen burner, the latter is automatically lighted from the flame of the illuminating burner, or vice versa, and whereby the illuminating burner may, also, serve as a heating means for an article positioned on said supporting attachment.

2. In a device of the class described, a gas inlet, an illuminating burner connected therewith, a Bunsen burner, provided with an attachment for supporting an article to be heated, also connected therewith and in such close proximity to the illuminating burner that when gas is ignited in the illuminating burner, and gas turned on to the Bunsen burner, the latter is automatically lighted from the flame of the illuminating burner, or vice versa, and whereby the illuminating burner may, also, serve as a heating means for an article positioned on said supporting attachment, and a single gas cock for controlling the supply of gas to both the illuminating burner and the Bunsen.

3. In a device of the class described, a gas inlet, an illuminating burner connected therewith, a Bunsen burner provided with a supporting attachment also connected therewith, said burners being so positioned with reference to each other that either may be automatically lighted from the other and when both are lighted they cooperate in heating an article which may be positioned on the supporting attachment, and a single gas cock whereby gas may be supplied to, or shut off from, either the illuminating burner or the Bunsen, or both.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
